Debian Decides; systemd vs. Upstart

OK, my .00002 cents worth. (sorry for the lengthyness of this post, it touched a nerve maybe or something close)
First, what is the problem with sysvinit?  OK, so systemd will do a complete userspace boot-up in 900ms.  So what?  Having personally tried systemd with VSIDO, I saw no ‘great’ benefits. OTOH, I have never tried Upstart.  (does using Upstart mean using Mir/Unity?)
Second, when you mention Upstart, all that I can think of is “we’re Shuttleworth’d”…
And third, why do we have to have one, or the other?  There are multiple choices now.  (As Digit so aptly mentions above)

Back to boot speeds, I read one posters comment, (on one of the other forums) and I’m paraphrasing here, if my system takes 3 to 5 minutes to boot, but once booted it remains solid and has no issues, then I don’t care.  Personally I think that the boot speeds that most people are talking about these days have more to do, generically, with UEFI than systemd. (yes, I know systemd drastically can reduce boot times, and have seen that with my own eyes) But, UEFI passes the boot off from the BIOS (read; slow) and directly to hardware, which, if your using an SSD, can seem instantaneous.  So, in a server environment, IMO, boot speeds tend to be irrelevant.  On a desktop (laptop) this becomes even more irrelevant.
